Remanufactured Axle Assembly 3.31 Ratio Ford 8.8" Rear

The Zumbrota Drivetrain RAA435-2244A is a remanufactured complete axle assembly specifically designed for the Ford 8.8 inch rear end. This unit features a 3.31 gear ratio and is compatible with ABS systems. Zumbrota Drivetrain's remanufacturing process emphasizes precision and reliability. Each axle assembly undergoes a rigorous inspection for straightness, cracks, and surface wear. Internal components, such as ring and pinions, internal gears, clutches, and carriers, are comprehensively inspected and tested. To ensure optimal performance and longevity, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The gear setup includes checks for optimal tooth contact patterns and correct rolling torque, established using inch-pound measurements, and proper gear backlash is set for quiet operation and adequate lubrication. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-enticed deep cleaning process on both internal and external parts, setting a high standard for axle assembly remanufacturing. All housings are inspected to ensure they meet OEM specifications for straightness and tested for surface wear and cracks.
